2 Claims. (01. 4-248),

This invention relates to bumpers providing stop means for limiting the rearward swinging movement of toilet seats and the invention has particular reference to a buffer or bumper of said character adapted to be attached to the flush valve of the toilet installation.

It has been the practice to manufacture flush valves with bumpers for said purpose formed as an integral part of the upper portion of the valve casing. Such construction, however, has the disadvantage that the bumper projecting outwardly beyond the surface of the valve casing renders it difficult to grind and polish the outer face of the valve necessitating a prolonged manual grinding and polishing operation so as to increase the cost thereof. In order to overcome these objections, the present invention provides a. holder or mounting adapted to be secured to the top of the flush valve in covering relation with the adjusting screw thereof and to which a bumper is releasably affixed. By this construction the outer surface of the valve body may be readily ground and polished without the inconvenience of an outwardly extending obstruction in the way of the grinding tool and the holder to which the bumper is releasably attached may also be readily ground and polished on the outer peripheral face thereof since the grinding and polishing may be performed before the attachment of the bumper therewith.

The invention further has in view the provision of a holder adapted to engage over the nut of the upper portion of the body of the flush valve and to be secured thereon by the means for attachment of the bumper thereto.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is a view of a flush valve partly in vertical section constructed in accordance with the invention.

Fig. 2 is a. horizontal sectional view therethrough taken approximately on line 2--2 of Fig. 1.

Referring to the drawings by characters of reference, the bumper is releasably secured in a holder In which is in the form of a cap secured upon the hexagonal shaped extension of the upper portion of a flush valve A. The holder consists of an annular top wall I I provided with an integral peripheral rim l2 formed with an outwardly projecting lip 13 extending peripheral-- 1y about the free edge of the rim.

A plurality of circumferentially spaced inwardly projecting beads l4 are formed on the inner face of the rim l2 which extend from the free edge of the rim to the top wall II. The rim i2 is also provided with an aperture l5 disposed substantially opposite the beads M for receiving therethrough an internally and externally threaded bushing l6 which is formed at its inner end with a flange l1 located within the holder to with the threaded portion of the bushing protruding radially through the aperture IS. A screw plug I8 protrudes inwardly through the threaded bore of the bushing l6 into engagement with the hexagonal shaped upper end of the flush Valve for securing the holder ID thereon. The screw plug I8 is formed with a kerf [9 in the outer end thereof for receiving a tool for turning the same so as toimpinge the inner end thereof against the hexagonal shaped upper end of the flush valve to thereby position the oppositely disposed angulated portion thereof between adjacent beads l4 with the adjacent faces of the said hexagonal shaped upper end portion bearing against the outer curved surfaces of the beads for preventing relative movement of the holder thereon and for positioning the cap with the bushing l6 projecting outwardly in the desired relation.

In addition to providing means for securing the holder It on the flush valve the bushing 16 also provides a mounting for a toilet seat bumper 20. The bumper is of cylindrical formation having a flanged inner end 2! which is arranged Within a cap 22 with the outer reduced end of the bumper projecting outwardly through an opening 23 in the end thereof. The cap '22 is internally threaded and is threadedly secured upon the bushing It in covering relation with the screw plug [8.

The bumper 20 is preferably composed of compressible resilient material such as natural or synthetic rubber so that the same does not mar the toilet seat when engaged thereagainst,v

and when so constructed the bumper may be readily replaced when the same becomes worn or damaged.

What is claimed is:

1. In a buffer, a cap adapted for engagement over a polygonal shaped body, said cap including a peripheral wall having a plurality of ribs alterhating with depressions on the inner face thereof and formed with an aperture therethrough disposed substantially opposite said ribs, an externally and internally threaded flanged bushing protruding through said aperture with the flange thereof disposed against said peripheral Wall, a plug threadedly engaged in said bushing and adapted to be tightened against said body for securing the cap thereon with an angulated edge of said body impinged between adjacent ribs,

an internally thneaded tubular member having a restricted opening' in its outer end tlireadedly' engaged over the outer end of said bushing, and a resilient buffer element protruding through said restricted opening in said; tubular member and having an enlarged inner'end for securing the same within said tubular membero 2. In a buffer, a cap adapted for-engagement over a polygonal shaped body, said cap including a peripheral wall having a gl raligy g peripheral ribs alternating with depressions on the inner face thereof and formed with an aperturetherethrough disposed substantially opposite said ribs; auflanged bushing arranged. in protruding.

relation in said aperture, a screw plug located in the bore of said bushing and adapted to be tightened against said body for securing the cap thereon with an edge of said body impinged between adjacent ribs, a tubular member secured over the outer end of said bushing, and a resilient bufier element having its inner end located in said tubular member with the,- outer free end thereof protruding therethrough.
